SIFTR-TOP POTVDEKCAIN Specification of Letters Patent.

Application filed November 1, 1910. Serial No. 550,151.

49.1 To all whom it may concern.'

Be it known that I, GEORGE W. WEBER, a citizen of the United States, residing in New York, in the county of New York and State of New York, have invented a new and useful Improvement in Sifter-Top Powder-Cans, of which the following is a specification.

My invention relates to improvements in sifter .top cans or containers for powder or other articles.

The object of the invention is to provide a sifter top can or container of a simple andl efficient construction, capable of being manufactured at small cost, in which the rotary closure sifter member or cap may be readily opened and be ,self closing and also have provision for holding orlocking it in its open position when it is not desired to hold it temporarily' open with the thumb or finger.

To practical] y accomplish this object or result, and herein my invention consists, I combine with the top head or cover of the container, which is provided with a fixed or non-rotary perforated sifter member pref'- erably in the form of a shouldered, cylindrical, central boss, a rotary closure siiter member or cap having a flange, the lower edge of which is crimped under the shoulder of the neck portion of the central boss to rotatably connect the cap with the boss,

the cylindrical wall of the central boss having a segmental slot provided with a locking notch at one end, and a combined spring and finger piece, preferably a fiat spring of the general shape of the major segment of' a circle, and secured at one end to the central boss and-having its finger piece end projecting out radially through the segn'iental slot iii the peripheral wall of the central boss, and also through a narrow upright slot in the flange of the rotary cap, the segmental slot in the boss permitting the rotary cap to be turned sufficiently by the radially projectingr fingerpiece to open and close the sii'ter o enings. .The rotary closure cap may be eld open by the finger piece temporarily with the thumb or finger, or it may be more permanently held open by simply depressing the finger piece into the. notch at the end of the segmental slot in the side wall of the central boss. The Hat spring is preferably .of reduced width at its finger piece end, so that the shoulder formed by in section.

the reduced end will serve to close the upright slot in the rotary cap through which projects.

My invention further consists in the nove?. construction of parts and devices and in 'the novel combinations of parte and devices herein shown and described and .lore particuiarly pointed out in the claims.

In the accompanying; 'drawing formino` 'a part of this specification, Figure 1 is a stide elevation of a sitter ,an or container en bodying my invention. Fig. 2 is apleoi View and Fig. 3 is an enlarged, det-ailtview more tightly flange of `the the finger piece .similar to F ig. 1, but .shmving the rotaryl section, and also piece end of' the spring t Fig. 4 is a. detail, horizontal section on line 4--4 of Fig. l, showing the position of the parts when the sitter Aopeninvs are closed. Fig. 5 is a similar View, shovfsifter member or cap in showing the finger ing the position of the parts when the sifter I h oles are open. F ig. 1s a sectional View, similar to Fig. 1l, showing a modification in which a washer or packing is interposed .between the cylindrical wall of the central boss and the cap fiange to further guard against leakage of` the powder.

In the drawing, 1 represents Athe body of a sifter top can or container having a bottom head 2 and top head or cover 3, provided with a fixed or non rotary perforated sifter member 4, preferably in the form of a raised central cyiindrical boss, having a dome portion 5, provided with sitter holes and having lts cylindrical or neck portion 'i' provided "with an annular shoulder 8.

The rotary siftcr member 9 is Yfurnished with sitter holes 10 in its domepoltion 1l, and with a cylindrical inward crimp or annular shoulder 13 en` gaging the anmilaishoulder 8 of the neck T to rotatably connect the cap 9 with the xed or non rotary sifter member.

The cylindrical wall or neck portion 7 of the fixed or non-rotary sifter member is provided above its annular shoulder 8 with a segmental slot 14, havin a lock notch or enlargement 15 at one en thereof for engagement with 'the finger piece 16 of the spring i7.

The spring 17 is preferably in shape the major segment of a circle, and it is securedat one end to the fixed sifter member 4, preferably at one extremity of the segf Patented July 21, 194. Y

flange 12, having an 9 mental slot 1i in its cylindricai Wall or neck T by means of' a hook or foid 18 at one end of the spring, which embraces an inwardly oli'set lip 19 in the cylindrical Wall or neck T of the fi.\:ed sitter member 4. The finger piece .1G is bent at an angle to the spring 17 and is preferably of reduced Width, thus forming a shouider 2O on the spring /adjacent to the iingcr piece, which aids in closing, powder-tight, the narrow upright slot 21 in the fiange 12 of the rotary closure sitter member or cap 9 through which the finger piece end of the spring projects. s

The ends of the segmental slot 14 serve by engagement with the finger piece as stops to limit the extent to which the rotary sitter member or cap may be turned in either direction. `When the finger piece 1G is in engagement with the stop shoulder at the left end of the sev'nientai slot 14, as shown in the drawing, the sitter openings in the rotary 'cap f) are out of register with the sitter openings in the fixed sifter member i, and the sitter openings are thus ciosed. ii n the iinger piece 1G is in engagement .a the stop shoulder at the right hand l of the segmental slot 14, the sifter holes f the rotary sitter member or cap 9 register with those in the iixed sifter member 4, and the sitter openings are thus open for sifting out the powder. The finger piece 1G may be held in its open position temporarily with the finger or thumb, or, if it is desired, the fing/'er piece 16 may be depressed into tht, ioni; or holding notch 15 of the segmenai dot ii, and the rotary cap will thus be sriif held in its' open position. To cause the rotary cap to ,self close, it is only necessary to release the linger piece by pushing it upward ciu. ot eue-agement with the shoulder oi the notch 'l if it has been depressed into said notch. Otherwise, the rotary cap self closes when the linger piece is let go.

'ii'hiie in practising my invention, I pre to rotatahljf' connect. the fixed and rotary .einer nieinlmrs by means of the interengagshouldered nec-lcs and flanges of said irte, and to construct the diti'erent parts 'ubsiantiaiiy as shown in the drawing, l be understood that my invention desire is not 'fouined to any pirtic-ular construcf 'ai oi' l" e'l or rotary sitter members or to Vartiwdar means shown for rotatably ino' the salue. ed, or in special cases Where re- ;d, to insure exccptionai powder tight-- ne of the cios-ure, a washer E-3 may be inn the eyiindricai wall of thev .l the cap tiauge to further eaii'agdas shown in 6.

This Washer' may preferabiy be of paper or like material and extend entirely around the circumference of the central boss. It should be made sufficiently narrow to move up and down with the finger piece 16. In operation, it turns With the rotary cap and finger piece.
